Patent GB-730054-A (GB)
Title: Method of processing glass fiber compositions
IPC: D21H13/40
Filed: 1952-11-24
Abstract: Cut bundles of glass filaments are mixed in water with a fusible resin which is added to the water before or shortly after the addition of the glass filaments in order to keep the bundles from disintegrating into individual filaments, said resin having an affinity for said glass fibres and the resin is then cured to an infusible form while in the wet state.  Finer water-wettable fibres such as envelope clippings, refined rag, kraft, cotton linters, caroa or other cellulose fibres, fine glass filaments or asbestos may also be present.  The compositions are felted or accreted and the preform obtained may be impregnated with further resin, which may be different, and moulded articles may thereby be obtained.  Resins specified are those derived from maleic anhydride, phthalic anhydride and ethylene or polyethylene glycol, together with styrene; butylated melamine resin together with a resin obtained from phthalic anhydride, glycerine and castor oil (example XIII); melamine-formaldehyde resin (example XV) and butylated melamine resin (example XVI).  Polyvinyl acetate is also included in examples XV and XVI.  Other monomers which may be substituted for styrene are vinyl toluene, naphthalene, ethyl benzene, chlorobenzene and xylene; a -methyl styrene; divinyl benzene, toluene, naphthalene, xylene, ethyl benzene, chlorobenzene, phenyl vinyl ether and diallyl phthalate. Suitable curing catalysts are benzoyl and acetylbenzoyl peroxides, cumene hydroperoxide and p-tertiary butyl perbenzoate and optionally a catalyst destroying agent such as air, hydrogen and sodium peroxides, sodium, potassium and ammonium persulphates, and sodium perchlorate and perborate may be used to destroy the catalyst at the surface of the coated filaments and thus preserve a sticky surface for incorporation of further resin.  Alternatively an uncatalysed polyester resin may be added to the felting bath just prior to felting.  Driers such as the lead and cobalt salts of 2-ethyl hexoic, oleic or naphthenic acid may be used with the impregnating resin. The glass filament bundles may be pretreated with polyvinyl acetate, vinyl trichlorosilane or stearato chromyl chloride to increase the affinity for the resin.  The fibres may be treated with a mordant such as stearato chromyl chloride or alum and a basic dye may be incorporated in the felting composition.  Alternatively an oil-soluble colour or a pigment, e.g. titanium dioxide, calcium carbonate or phthalocyanine derivatives, may be incorporated in the resin.  The products may be used in paper making, filtering oil and water and for making moulded articles, e.g. cases, cabinets, sleds, hobby horses and baby-carriage bodies.  Specification 723,955, [Group VIII], is referred to.

Abstract: 1473136 Photo-detector bias circuits ASAHI KOGAKU KOGYO KK 5 July 1974 [6 July 1973] 29974/74 Heading G1A A bias circuit for a PN junction photo-detector is arranged to provide the same voltage at both terminals of the detector so that it operates in a short-circuit mode. In such a mode dark current effects are reduced; the bias circuit is arranged to operate with a low supply voltage and to be temperature insensitive. In Fig. 2 FET Q1 supplies a constant current to diode connected transistor Q4; this biases a transistor Q3 to a constant current mode, and this current is supplied by a FET Q2. If the two FETs are a matched pair, and if R1 = R2, the voltages at point A (the collector of Q3) and point C (the gate of Q2) are the same, and the photo-detector diode PD could be connected between these points. In Fig. 2 a buffer formed of a PNP/NPN matched pair Q5, Q6 is connected between point A and the detector cathode. The detector output current flows through a diode Q7 to produce a voltage across Q7, this voltage varying logarithimically with the output current. Temperature effects in the circuit are avoided by the use of matched FETs, and because Q3 and Q4, and Q5 and Q6, compensate one another.
